Motor Sizing Calculations

The speed of Induction Motors and Reversible Motors vary with the size of the load torque. So, the selection should be made between the rated speed and the synchronous speed. There can be a difference of continuous and short-term ratings, due to the difference in motor specifications, despite the fact that two motors have the same output power.Motor Sizing Calculations - Alaa Khamis,The speed of Induction Motors and Reversible Motors vary with the size of the load torque. So, the selection should be made between the rated speed and the synchronous speed. There can be a difference of continuous and short-term ratings, due to the difference in motor specifications, despite the fact that two motors have the same output power.Electric Motors and Drives - UF MAE,Electric Motors and Drives . To calculate the peak power and torque produced by an electric motor, you will need to know the following: • Motor supply voltage : V s [V] • Peak motor current: I s [amps] • Motor velocity: N [rpm] The power produced by the motor can be calculated as: P [watts] = V s [volts] × I
